Saving electricity in the household

Do you know the energy guzzlers in your household? Is your fridge set up correctly? Do you prefer bathing or showering? Here are the most important questions and answers on the topic of saving electricity

Anyone who saves electricity at home not only does something for their own wallet, but also for our environment. After all, those who reduce their own CO2 balance do their part to reduce global CO2 emissions. After all, a significant part of Germany’s electricity continues to be generated from fossil fuels, the processing of which releases harmful greenhouse gases. Here are tips for efficiently saving electricity in your own four walls. Cooking accounts for the largest share of electricity consumption in private apartments and houses at around 30 percent, followed by refrigerators and freezers (20 percent) and information and communication technology such as televisions, computers and Internet routers (17 percent). Hot water consumption in the kitchen and bathroom is in fourth place with around 12 percent.

Refrigerators are energy guzzlers

As a result, the most electricity can be saved in the kitchen. And here are a few tips for noticeable reductions. Don’t preheat your oven anymore and choose convection instead of top and bottom heat. Turn off the burners 10 minutes before the end of the cooking time to cook with the residual heat. Only use pots with lids – this is more than 50 percent more economical than cooking with open pots. One of the biggest energy guzzlers in many households are refrigerators or fridge-freezers – after all, they usually run around the clock and, apart from holidays, all year round. If the devices are too old or incorrectly adjusted, this can become really expensive and harmful to the environment. Make sure that your cooling devices are placed correctly, i.e. not directly next to heat sources such as the stove or radiator. In a normal refrigerator, 6 or 7 degrees is enough, the freezer does not have to be set colder than minus 18 degrees. And: Defrost older freezers regularly, as a layer of ice increases power consumption significantly.

Energy efficiency classes for devices

Since 2017, a new EU energy label regulation has regulated the labeling of household appliances. Category A is given to devices with the lowest consumption. Based on a traffic light, the energy saving is also shown in color from green to red. The regulation replaces the old one, according to which there were also ratings from A+ to A+++ in the highest efficiency class. In retail, most electrical devices must bear the new label from March 2021.

Turn off standby devices

There is also potential for savings in the living room and study. This is not least due to the fact that more and more devices have a stand-by function. This means that they are always ready to switch on without delay, but they also always consume electricity. This can be remedied by multiple plugs with on/off switches: simply set to off at night or when you leave the house. Experts estimate that stand-by mode accounts for around 10 percent of the electricity bill on average. Even with 5 devices that are switched off from time to time, this can save up to 220 kilos of CO2 emissions a year. Another trap: the mobile phone charger. Do you leave it plugged in all the time? Then you waste electricity and money. Because the charger consumes energy via its transformer, even if no end device is connected.

Washing machine fully loaded

The following applies to washing machines: Only switch on when the drum is really full. And: Wash more often at 30 degrees. This is sufficient in many cases, especially with modern devices. After all, the majority of the electricity consumed by washing machines is used to heat the water. You can usually give yourself a pre-wash. The tumble dryer is also a big energy guzzler (at around 60 euros a year). The good old drying rack is an energy-efficient and practical alternative, especially in spring and summer.

Better to take a shower than a bath

In the bathroom, it helps to use the bathtub less and use the shower instead. Flow limiters (also called aerators) for taps add air to the water jet and significantly reduce the amount of water flowing through. This not only reduces the costs for heating the water, but also the bill for water and waste water. By the way: If you replace your old instantaneous water heater with a modern, fully electronic device, you not only save energy, but also receive a subsidy of 100 euros from the federal government. More information and the application is available at .

Green electricity is trendy

But if you really want to obtain sustainable energy, you should take a close look at the providers. More and more environmentally conscious Germans are switching to providers who supply green electricity generated from renewable energies such as wind, hydroelectric power or solar cells. But be careful: The term “green electricity” is not legally defined or protected. This can also hide an electricity mix that is not 100 percent ecological, but is partly generated with conventional energy sources such as coal, oil or natural gas. If you want to be on the safe side here, you can use environmental seals as a guide. The “green electricity label” or the “ok-power seal” ensure, for example, that the energy sources of the provider actually.

Practical tips

1. Consumption check

The “MY ELECTRICITY CONSUMPTION” app (Android) reliably calculates how high the consumption of individual devices and rooms is. All you have to do is enter the wattage and the operating time in hours.

2. Smart calculator

“ENERGY COSTS CALCULATOR” works in a similar way, the app is suitable for IOS devices. Simply enter the service and the app will display the costs for freely selectable periods.

3. Label-Scanner

“Ecogator” for IOS devices scans the energy label of devices and helps to understand and evaluate the efficiency classes. In this way, the power consumption can be determined and compared at the time of purchase.

4. Multifunctional

” Energy check co2online ” (IOS and Android) compares consumption data for electricity, heating energy and water. With scanning function for counters.

5. Find cheap providers

Although the price of electricity increases almost every year, many households stay with their old electricity supplier for convenience – often with an expensive basic tariff. The easiest way to switch is to use an online comparison calculator. Large comparison portals are e.g. B. or .
